VENTILATOR.

Application filed May 10,

My present invention pertains to ventilators for rooms, apartments and, the like and it contemplates the provision of an extremely inexpensive device easily and readily operated and one that is adapted to ventilate the room, apartment and the like by permitting fresh air to enter the room and the foul alr to pass from the room and this without liability of causing the occupants of the room to expose themselves to colds and the like caused by drafts.

The invention in all of its details will be fully understood from the following description and claims when the same are read n connection with the drawings accompanying and forming part of this specification, in which Figure l is a side elevation of my novel ventilating` device as the same appears when arranged in a window and from the inside of the room.

Figure 2 is a view looking down on my ventilator.

Figure 3 is a view similar to Figure 2 but showing the ventilating elements in transverse section.

Figure 4 is a view taken in the plane indicated by the line 4-4 in Figure 3.

Figure 5 is a similar view taken in the plane indicated by the line 5-5 of Figure 3.

Figure 6 is a sectional view taken in the plane indicated by the line 6-6 in Figure 2.

Similar numerals of reference indicate corresponding parts in all the views of the drawings.

My novel ventilator is designated as a whole by 1 and comprises the sections 2 and 3. The said member 1 is beveled at 4: and 5 so at to be' snugly engaged by the sill of a window at the lower end and against the lower portion of the iframe of, a window at the upper end; it being understood that the device is adapted to be seated into the space that is present between the sill and frame of the window when said window is raised or elevated above the sill. The sections 2 and 3 are united with respect to each other by means of the sleeve member 6 and the said member 6 carries the cleats or bumpers 7, as shown. Provided in the upper and lower edges of the members 2 and 3 are grooves 8 that eXtend approximately the width illustrated and the bumpers 7 rest in these grooves and are adapted to engage the shoulders at the ends of the grooves 8 to limit endwise movement of the members 1927. Serial No. 190,255.

2 and 3 with respect to the sleeve 6. Adapted to assist in the increasng or decrcasing of the length of the ventilatng device so as to accommodate the same for vari-- o-us widths of window frames, I provide on each. of the sections 2 and 3 of the ventilator the handles 9. v 1

.Although I have illustrated and described a device adapted to be adjusted with respect to a window iframe, I would distinctly have it understood that my novel ventilating elements hereinafter described may be mounted or arranged on any 'orm of board compatible with the purpose off the invention.

Monnted on the section 2 and on the room side thereof is a cylinder 10` while on the section 3 is a cylinder 11 and each of the cylinders 10 and 11 terminate in upstanding funnel portions 12 and 13 while both of the cylinders are provided with slots 14 and 15 respectively in which knobs or handles 16 and 17 actuate. Interiorly as clearly shown in Figure 3 the cylinders 10 and 11 are provided with laterally bent ends 18 and 19 that are secured to the sections 2 and 3 by means of the fastening elements 20 and 21 whereby the entire ventilating cylinders are secured on the sections 2 and 3.

Secured to the knobs 14: and 15 of the cylinders are movable cylinders 22 and 23 and the said cylinders 22 and 23 turn within the cylinders 10 and 11 and are provided with the cut-out portions 24: and 25. The said cut-out portions 24: and 25 are arranged on the cylinder 22 while the cylinder 23 is provided with the cut-out portions 26 and 27. 'The section 2 is provided with an opening 28 while the section 3 is provided with a similar opening 29 and mounted in the said openings is screening 30 and 31. On the outer side of the sections 2 and 3 are hoods 32 and 33 respectively that are fastened to their respective section by means of fastcnings 34 and 35 while adapted to enter the interior of the hood 32 are wings 36 while at the lower end the hood 33 isprovided with the cut-out portion 37.

In the practical operation of the invention, the sections 2 and 3 are arranged in the window frame resting upon the sill and properly adjusted with respect to the width of the window frame. If it is desired to' ventilate the room it is merely necessary to manipulate the knobs 16 and 17 to make a continuous opening from the cylinders to the hood. The fresh air will enter the apartment through the hood 33 while the foul air will be forced from the apartment by means of the ventilator element 32. It will he nanfest that because of the wings 36 fresh air will not enter through the hood 32 whereas due to its Construction the hood 33 will permit fresh air to enter the apartment. It will be gathered from the foregoing that the device is extremely simple in Construction and arrangement and that a room equipped with our novel ventilator will be at all times properly ventilated and that the ventilating action will not allow drafts, sleet, Snow rain, dust and the like from entering the apartment; these latter elements striking the screens and 31 to prevent same from gaining access to the apartment.

Having described my nvention what I claim, is

1. A ventilator comprising two sections adjustable with respect to each other and having openings therein, screens mounted over the openings, cylinders mounted on the sections, other cylinders arranged within the first cylinders, and novahle with respect thereto and having openings adapted to communicate with the openings of the sections, funnel portions mounted on the first cylinders and communicating therewith and hoods arranged on the sections; one of which is provided with interier wings and the other of which is provided with a cut-out portion and being so constructed and arranged that they communicate with the openings in the sections.

2. A ventlator comprising adjustable sec tions, cylinders mounted on the sections and terminated in upstandng portions open at their upper ends; said cylinders communicating with an opening in the sections, means for closing the passages of the upstanding portons and mounted within the cylinders and hoods arranged on the sections in rear of the cylinders and having open sides that communicate with the openings of the sections and means arranged in one of the hoods for eXhausting air from the cylinders.

3. A ventilator comprising adjustable sections having openings therein, screens mounted over the openings, cylinders secured to the sections and having openings that communicate with those of the sections and also having funnel portions open at their upper ends, means mounted in the oylinders for closing the passage through said cylinders and for establishing the passage through said cylnders, hoods arranged on the sections and having openngs that communicate with those of said sections; one of said hoods having wings arranged therein and the other of said hoods having a cut-out lower portion.

In testimony whereof I have hereunto set 1. hand. ny FRED DECELLE.
